What are the two major factors determining the distribution of terrestrial biomes? There are two major factors that determine what type of biome an area has: latitude and elevation. A place’s latitude determines the climate and therefore what kinds of plants and animals can live there, whereas elevation determines what types of plants can thrive there. As a result, many areas have only grasses or shrubs instead of forests because mountains prevent tree growth. A biome’s distribution can also be affected by the amount of rainfall, the type of soil, and nearby water bodies. Deserts, for instance, occur in low…

Which molecules do not normally cross the nuclear membrane? A nuclear membrane’s primary function is to act as a barrier between the nucleus and the rest of the cell. This means that only certain molecules can enter the nucleus across the membrane. Cytoplasmic molecules are those molecules that do not normally cross the nuclear membrane. Among them are most proteins and all of the cell’s DNA. These cytoplasmic molecules are specifically kept out of the nucleus by the nuclear membrane. This is achieved by a number of features, such as: The membrane has a selective permeability in which only certain…

Which processes lead to most genetic variation in sexually reproducing organisms? Within sexually reproducing organisms, the most genetically variable individual is typically the male. This is due to the fact that the X-chromosome in females can be passed on regardless of whether it’s paired with a Y chromosome. As males have only one X-chromosome, they must contribute their other chromosome (either an X or Y) during reproduction in order to pass on genetic code. To reproduce successfully, males need two copies of each gene they carry, while females only need one copy of each gene. What is genetic variation? Genes…

What do fats, steroids, and waxes have in common? Do you know what do fats, steroids, and waxes have in common? All of them are lipids. Among the many types of lipids are fats, steroids, and waxes. All of them are soluble in organic solvents, such as alcohols and ethers, but not in water. Nonpolar molecules are soluble in organic solvents. Lipids play a crucial role in the body. They are the main component of cell membranes, and they are also critical for storing energy. A steroid is a type of lipid that plays a role in hormone production. Wax…

Human subjects research ethics regulations can be traced back to the Nuremberg Code, which was created in response to the atrocities committed by Nazi doctors during the Holocaust. Research on human subjects is governed by the Nuremberg Code, a set of ethics principles. The guideline stipulates that the consent of the participant is essential, that the experiment should be designed to avoid foreseeable risks, and that the researcher must take into account the participant’s welfare. In 1964, the World Medical Association (WMA) produced the Declaration of Helsinki following the Nuremberg Code. The Declaration of Helsinki specifies specific ethical principles for…
